DECLARE @geographyData geography; 
//Convert wkt to geography 

SET @geographyData = geography::Parse('LINESTRING(-132.360 50.657, -120.340 47.659)');


//Convert back to wkt from geography

(1) @geographyData.ToString();

(2) @geographyData.STAsText();

(1) 和 (2) 给我相同的结果，即 LINESTRING (-132.36 50.657, -120.340 47.659)。ToString() 和 STAsText() 有什么区别？

谢谢。
